Dust collection with a Thien Cyclone Separator and a short shop tour
For the last 3 years since I’ve gotten into woodworking I’ve made do with an old 1HP Grizzly dust collector. It worked well enough when connected to one tool at a time. Up until recently that hasn’t been a problem. I left it connected to the table saw and used my shop vac on the router table. The only other power tool I had was a thickness planer with very poor dust collection anyway.
But in the last 6 months I’ve added a couple tools to the shop, namely a power jointer and a bandsaw. My first attempt at dust collection was 4″ PVC from my 1HP DC to the table saw and jointer, with blast gates. It wasn’t very successful for lots of reasons. (underpowered DC for the long runs, not good enough seals on the joints, etc…)
So for the last month or so I’ve been reworking the entire shop. I got a new single stage DC (the Grizzly 3HP double canister ), reworked the entire shop with 6″ metal ducting, and built a Thien Cyclone Separator.
Actually I built two of them, one for my new system that is based on 6″/7″ ducting ports and a second one based on 4″ ports that I’m handing off to my father-in-law for his woodturning shop.
Building them was pretty simple, if a bit time consuming, and it generated a TON of MDF dust. Eventually I started working outside just so I quit filling the shop with fine dust.
Honestly the priming, painting and glueing took the longest. It turned a quick 4-6 hour project into a week long adventure, but I’m happy with the results.
I shot a quick video of my top hat in action for anyone thats interested. Sorry for the poor video quality, I didn’t feel like busting out the DV camera and messing around with Firewire, etc… so I just shot it with my iPhone.
